CVE-2024-44102Network attack vector

SYSTEM code execution via unsafe .NET deserialization

Published Nov 12, 2024 · Updated Nov 15, 2024

Insecure deserialization in Siemens TeleControl Server Basic before 3.1.2.1 allows remote attackers to execute code as SYSTEM. The redundancy-enabled server deserializes attacker-supplied .NET objects received over the network, allowing object construction to invoke arbitrary code. Exploitation is unauthenticated and requires redundancy to be configured; successful execution grants full SYSTEM privileges on the server.
